BENCH-PLATE SOCKET.

SPECIFICATION forming part of Letters Patent No. 277,675, dated May 15, 1883.

Application filed February 27, 1883.

To allwhom it may concern Be it known that I, JAMES H. BUCKLEY, of Bangor, in the county of Penobscot and State of Maine, have invented certain new and useful ImprovementsinBench-Plate Sockets; and I do hereby declare that the followingis a full, clear, and exact description of the invention, that will enable others skilled in the art to which it appertains to make and use the same, reference being bad to theaccompanyingdrawings, forming apart of this specification, in which- Figure 1 shows abottom plan of bench plate and lugs; Fig. 2, a diagonal elevation on line A B, wooden bench in dotted lines; Fig. 3, isometrical perspective of one of the jaws.

Same letters show like parts.

My invention consists of an improved socket for bench-plates, adapted to receive and hold staking-tools, shears, &c.,designed for the use of tinsmiths, coppersmiths, and others, selfadjusting to tools varying in size and taper of shank to a considerable degree, and holding them firmly and securely. This the ordinary bench-plate will not do, allowing, as it does in almost every case, alarge degreeot' wabble to the tools, unless they have been specially fitted in each case, and then, even, they will inevitably loosen by wear.

My invention will be understood by reference to the drawings.

At a is shown a portion of abench-plate, the dotted lines a showing the bench to which it is attached; I) b, lugs east on the under side thereof, passing down into the bench at, and slotted at c 0. These lugs are placed at opposite corners of the mortise 3 in the benchplate, which receives the tool, the slots 0 c being in a plane diagonal with said mortise. At d d are angle-irons having an internal taper from top to bottom, the top being larger, placed at a slight distance apart and having (No model.)

lips e, cast at their outer angles, fitting loosely the slots 0 c, and pivoted therein at f f.

When the tool is placed in the socket'the 5 latter expands at top or bottom,as the case may be, to accommodate itself to the shape of the tool-shank, which it holds firmly in place with a metallic bearing on all sides, and this without assistance from the edges of the benchplate mortise.

It is obvious that it is not essential to my invention that the socket should be cast with the bench-plate, as it would be equally effective if cast on a separate plate smaller in size and adapted to be inserted in the bench a, under the mortises of the bench-plate proper. In such case it might be well to cut away the opening in such smaller plate and elongate the jaws d (I, so that their upper ends would reach nearly to the under side of the bench-plate proper. It is also evident that the particular form describedis not of the essence of my invention, as tools with round shanks can be held upright in like manner as those of rectangular shape with very slight and unimpor' tant change, the cross-section of the socket being made to conform to the shape of the tool sutficiently to secure it firmly for the purpose for which it is to be used. These mere mechanical changes, not involving invention, I consider as mere equivalents.

What I claim as my invention is- An improved bench-plate socket for stakingtools, shears, &c., embodying the plate, lugs, and pivoted self-adjustingjaws, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 22d day of February, 1883.
